The Mutsuki class was an improved version of the Kamikaze-classdestroyers and was the first with triple 61-centimeter (24 in) torpedo tubes. The ships had an overall length of 102.4 meters (335 ft 11 in)[1] and were 94.54 meters (310 ft 2 in) between perpendiculars. They had a beam of 9.16 meters (30 ft 1 in), and a mean draft of 2.96 meters (9 ft 9 in). The Mutsuki-class ships displaced 1,336 metric tons (1,315 long tons) at standard load and 1,800 metric tons (1,772 long tons) at deep load.[2] They were powered by two Parsons geared steam turbines, each driving one propeller shaft, using steam provided by four Kamponwater-tube boilers. The turbines were designed to produce 38,500 shaft horsepower (28,700 kW), which would propel the ships at 37.25 knots (68.99 km/h; 42.87 mph). The ships carried 420 metric tons (413 long tons) of fuel oil which gave them a range of 4,000 nautical miles (7,400 km; 4,600 mi) at 15 knots (28 km/h; 17 mph). Their crew consisted of 150 officers and crewmen.[3]
The main armament of the Mutsuki-class ships consisted of four 12-centimeter (4.7 in) Type 3 guns in single mounts; one gun forward of the superstructure, one between the two funnels and the last pair back to back atop the aft superstructure. The guns were numbered '1' to '4' from front to rear. The ships carried two above-water triple sets of 61-centimeter torpedo tubes; one mount was between the forward superstructure and the forward gun and the other was between the aft funnel and aft superstructure. Four reload torpedoes were provided for the tubes.[3] They carried 18 depth charges and could also carry 16 mines. They could also fitted with minesweeping gear.[4]
Construction and career
Mutsuki, built at the Sasebo Naval Arsenal, was laid down on 21 May 1924,[2]launched on 23 July 1925[4] and completed on 26 March 1926. Originally commissioned simply as Destroyer No. 19, she was assigned the name Mutsuki on 1 August 1928.[3] In the late 1930s, Mutsuki participated in combat in China, including the First Shanghai Incident of 1932 and other actions in the Second Sino-Japanese War.
At the time of the attack on Pearl Harbor on 7 December 1941, Mutsuki was the flagship of Destroyer Division 30 under Destroyer Squadron 6 of the 4th Fleet. She sortied from Kwajalein on 8 December as part of the Wake Island invasion force, carrying an advance landing party of the Japanese Special Naval Landing Forces (SNLF). Early on the morning of 11 December, the American garrison repulsed the first landing attempts by the SNLF, which was supported by the light cruisersYūbari, Tenryū, and Tatsuta and the destroyers Yayoi, Hayate, Kisaragi, Mutsuki, Oite, and Mochizuki, two old Momi-class vessels converted to patrol boats (Patrol Boat No. 32 and Patrol Boat No. 33), and two troop transports containing 450 SNLF troops. After taking heavy losses (including Kisaragi and Hayate), the Japanese force withdrew before landing. This was the first Japanese defeat of the war, and also the only occasion in World War II when an amphibious assault was repulsed by shore-based guns.[5]Mutsuki returned on 23 December with the second Wake Island invasion force, and again carried a SNLF advance landing party before returning to Kwajalein.[6]
During the Battle of the Coral Sea from 7–8 May 1942, Mutsuki was assigned to the Operation Mo invasion force for Port Moresby. After that operation was cancelled, Mutsuki remained based out of Rabaul, escorting shipping between Truk, Rabaul and Palau until recalled to Japan in July for a brief refit.[6]
